摘要:
An apparatus adapted for use with a cartridge, e.g., in loading a cartridge in a camera, includes an engagement portion settable in either a first state or second state and engageable with a film cartridge loaded in a cartridge chamber, and a restriction device that either (1) restricts a loading operation of a cartridge into the cartridge chamber when the engagement portion is in the second state, or (2) restricts engagement of the cartridge with the engagement portion where the engagement portion is in the second state.

A camera or an apparatus adapted to use a film cartridge, or a unit applicable to the camera or the apparatus, includes a first device for engaging the film cartridge, and a second device for at least one of loading and unloading the film cartridge with respect to the camera by automatically moving the first device together with the film cartridge.

A camera includes a motor, a first planetary gear which revolves on the basis of an output rotation of the motor, a second planetary gear which revolves on the basis of the output rotation of the motor, a first camera operating mechanism which engages with the first planetary gear by the revolution of the planetary gear caused by a rotation of the motor in a first direction, a second camera operating mechanism which engages with the second planetary gear by the revolution of the second planetary gear caused by the rotation of the motor in the first direction, and a selector for selectively preventing the revolution of either of the first and second planetary gears. The selector selectively permits the operation of either of the first and second camera operating mechanisms during the rotation of the motor in the first direction.
摘要:
A camera incorporating a capacitor for flashing a flash device is arranged to have the capacitor disposed within a hollow portion of a film take-up spool, to have a power source battery accommodating space provided in the vicinity of the spool, and to have a motor which serves at least as a film transporting drive source disposed in the vicinity of a film cartridge stowing chamber.
摘要:
A camera having a built-in winding unit wherein at least a sprocket and a spool of the winding mechanism are provided on a first base plate and a space is formed between the first base plate and second base plate, whereby a part of the winding mechanism is built into this space.
摘要:
A film transporation device for a camera having an operating member adapted upon changeover thereof to a rewinding position to render a sprocket freely rotatable so that rewinding of a film is possible and a locking member for holding the operating member in the rewinding position, wherein a member is provided upon winding-up of the camera to move forward as it is operatively connected to a winding system and upon termination of the winding operation to move backward under the action of a bias force of a spring member as the operative connection is severed, whereby the backward movement of this member operates to release the operating member from the connection with the locking member, thereby enabling superimposition of a number of photographs.
摘要:
A single lens reflex camera with a built-in winding motor performing quick return of the mirror and automatic diaphragm in the initial stage of winding operation where the load on the winding motor is very little is disclosed.
摘要:
A camera of the type having a winding motor is provided with a timer circuit which, after the lapse of a predetermined length of time, forcibly effects a supply of power to the winding motor when the shutter blades fail to travel in a normal way, and even when a signal corresponding to shutter blade travel completion is not obtained. The winding motor then resets the camera mechanisms which are arranged to perform various operations, such as shutter charging, mirror returning and film feeding, into their respective initial states. This eliminates the possibility of trouble resulting from such a malfunction of the camera that it becomes inoperative halfway through completion of photographing operation.
摘要:
A film magazine holding device for a camera wherein the film magazine loading chamber is provided with a spring member for pushing the film magazine against the upper surface or the lower surface of the loading chamber so as to prevent the opening in the film magazine, through which the film is drawn out of the magazine, from being brought out of a determined position in the opened and the closed state of the back cover.
